Synthetic Patch Rotator Cuff Repair: A 10-year Follow-Up

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Massive irreparable rotator cuff tears pose significant challenges in orthopedic surgery.
• Synthetic patches are explored as tendon substitutes to bridge these defects.
• Long-term outcomes of synthetic patch use require further investigation.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of synthetic patches used for rotator cuff repair.
• To assess functional and clinical outcomes in patients with irreparable rotator cuff defects treated with synthetic patches.

Main Methods:

• A cohort of patients who underwent rotator cuff repair using synthetic patches (ePTFE or PTFE Felt) were followed up.
• Minimum follow-up duration was 8.5 years postoperatively.
• Outcomes assessed included shoulder pain, function, range of motion, strength, and imaging.

Main Results:

• Five patients with a mean tear size of 27 cm² were followed for an average of 9.7 years.
• All synthetic patches remained in situ, with no requirement for revision surgery.
• Significant improvements in shoulder external rotation and abduction were observed compared to pre-operative status.

Conclusions:

• Synthetic patches demonstrate durable and effective long-term results for bridging massive irreparable rotator cuff defects.
• Patients experienced reduced pain and improved shoulder function post-implantation.
• The use of synthetic patches in this cohort resulted in sustained repair integrity and positive functional outcomes.
